Waveplate

タイトルまたは説明

Waveplate (retarder or phase shifter) is an optical device that alters the polarization state of a light wave traveling through it. Waveplate works by shifting the phase of the light wave between two perpendicular polarization components. 
 
Waveplate is made from material of birefringent crystal with a carefully chosen thickness. The birefringent crystal has the ordinary and extraordinary axes. The velocities of light polarized along the two axes are different. This difference in velocities gives rise to a phase difference when the two beams recombine. In the case of an incident linearly polarized beam this is given by α=2πd(ne-no)/λ, where α is phase difference; d is thickness of waveplate; ne, no are refractive indexes of extraordinary and ordinary rays respectively; λ is wavelength. At any specific wavelength the phase difference is governed by the thickness. They are widely used in Circulator, Interleaver, Transceiver, DGE, DCE, etc.
 
Advance designs and provides various types of waveplates, including octadic-wave (l/8), quarter-wave (l/4), half-wave (l/2) and full-wave (l) plates with available wavelengths from **0nm****0nm.
